VERTICAL SIDEWALL INSTALLATIONS

STEP 1

Locate vent opening on the wall. It may be necessary to

rst position the replace and measure to obtain hole location. Depending on whether the wall is combustible or non-combus- tible, cut opening to size. (Fig. 22)

(For combustible walls rst frame in opening. Fig. 22).

Fig. 22

COMBUSTIBLE WALLS : Cut a 9-3/8"H x 9-3/8"W (240

mmx 240 mm) hole through the exterior wall and frame as shown (Fig. 22).

NON-COMBUSTIBLE WALLS : Hole opening should be

7.5" (190 mm) in diameter.

STEP 2

Measure wall thickness and cut zero clearance sleeve parts to proper length (MAXIMUM 12” / 305 mm). Assemble sleeve and attach to restop with #8 sheet metal screws (supplied).

Install restop assembly (Fig. 23).

Zero clearance sleeve is only required for combustible walls.

STEP 3

Place replace into position. (Fig. 24). Measure the vertical height (X) required from the base of the ue collars to the centre of the wall opening.

Fig. 24

STEP 4

Apply a bead of silicone to the inner and outer ue collars of the replace and using three (3) screws attach an appropriate length of vent to the replace. Follow with the installation of the inner and outer elbow, again secure joints as described in the section 'Joining DV Components'.

STEP 5

Measure the horizontal length requirement including a 2" (50

mm)overlap, i.e. from the elbow to the outside wall face plus 2" (50 mm)(or the distance required if installing a second 90º elbow. (Fig. 25).

Always install horizontal venting on a level plane.
